It took me sometime ....sorry.🙁
Finally my amplifier click relay when offset is 8mv.
This give a little pump.To fix this just increase the value of C5 on the protection board.
i don't know if Elbert still around.....
I am building a new Crescendo Millennium and i have the same problem then Elbert had with one card, it is not possible to adjust the idle current down to get a voltage reading between 45-55 mV as specified...because i have 65mV already and the problem is that I get an idle current of 300-350 mA at a pot meter setting at max value, is that the only solution is to change R28 with 1k value, or from the date of this thread, 2011, somebody have find an other solution to this problem..
thank for your help....
